Abstract
A copper alloy is disclosed, which contains 0.1 to 3.0 wt % of Ni, 0.1 to 1.0 wt % of Ti, the ratio of Ni to Ti being 4.ltoreq.Ni/Ti thereby, 0.1 to 6.0 wt % of Sn, and 0.005 to 3.0 wt % in total of one or more elements selected from the group consisting of Zn, Mn, Mg, Ca, RE, B, Sb, Te, Si, Co, Fe, Zr, Ag, Mm and Al, and consists of the remainder of Cu and the inevitable impurities. The method for the manufacture of the alloy is characterized in that, after copper alloy ingot was maintained and homogenized for 0.5 to 15 hours at 750.degree. to 960.degree. C. prior to rolling, the hot rolling is carried out starting from a temperature of 700.degree. to 880.degree. C. and the cooling is made immediately after the end of rolling.
